how to speed up rusting

Iron (or steel) corrodes more quickly than most other transition metals and readily does so in the presence of both oxygen (in air) and water to form an iron oxide. Rusting is speeded up in the presence of salt solution. Rusting is Fe (s) + O 2(g) + H 2 O (I) Fe ..

Who has not seen the damaging effects of rusting of iron! During the process of rusting the oxide that forms is brittle and chips off from the surface. This exposes yet another layer below to the deleterious effects of moisture and air. Thus, rusting destroys the metal..

Rusting can be prevented, by applying a protective coating on the surface of the iron, so that the iron does not come in contact with air and moisture simultaneously. This coating can be of two types: (i) Non-metallic coating (ii) Metallic coatin..

On multiplying the first equation by 4 and adding to the second, The dissolved O 2 can take electrons directly also 4. Fe 2 + reacts with dissolved O 2 and wat..

* The presence of water and oxygen is essential for the rusting of iron. * Impurities in the iron, the presence of water vapor, acids, salts and carbon dioxide hastens rusting..

The presence of water and oxygen is essential for the rusting of iron. Impurities in the iron, the presence of water vapor, acids, salts and carbon dioxide hastens rusting. Pure iron does not rust in dry and carbon dioxide free air. It also does not rust..

Speed can be defined as the distance covered by a moving object in unit tim..

In an athletic meet different participants start running at the same time and cover the same distance. The person who takes the minimum time to cover the distance will be judged as the winner. Suppose Ram and Krishna take 20 minutes and 10 minutes respectively to cover a distance of 1000 m, who is ..
